* SECTION: BaseWindow
* @title: AnacondaBaseWindow
* @short_description: Top-level, non-resizeable window
*
* A #AnacondaBaseWindow is a widget that contains other widgets and serves as
* the base class from which all other specialized Anaconda windows are
* derived.
*
* The AnacondaBaseWindow consists of two areas:
*
* - A navigation area in the top of the screen, consisting of some basic
* information about what is being displayed and what is being installed.
*
* - An action area in the majority of the screen. This area is where
* subclasses should add their particular widgets.
*
* <refsect2 id="AnacondaBaseWindow-BUILDER-UI"><title>AnacondaBaseWindow as GtkBuildable</title>
* <para>
* The AnacondaBaseWindow implementation of the #GtkBuildable interface exposes
* the @nav_area as an internal child with the name "nav_area" and the
* @action_area as an internal child with the name "action_area".
* </para>
* <example>
* <title>A <structname>AnacondaBaseWindow</structname> UI definition fragment.</title>
